Application filed June 19, 1917. Serial No. 175,617.

To all whom it may concern:

l 3e it known that I, PAUL T. ULRICH, a citizen of the United States, and resident of Miami, in the county of Dade and State of Florida, have invented certain new and useful Improvements in Key-Fasteners, of which the followin is specification.

This invention re ates to the class of locks and latches and has particular reference to new and useful improvements in key fastenors.

The primary object of my invention is to provide a device of the character mentioned that is hingedly secured to a door knob and iadapted to be detachably associated with the For the purpose of illustrating my invention, I have shown in the accompanying drawings one form thereof which is at pres ent preferred by me, since the same gives in practice satisfactory and reliable result, although it is to be understood that the various instrumentalities'of which my invention consists can be variously arranged and organized and that my invention is not limited to the precise arrangement and organization of these instrumentalities as herein shown and described.

Other novel features of advantage and construction will more clearly hereinafter ap ear in the detailed description herein.

n the accompanying drawmgs:

The view is a perspective showing my in vention applied to a door knob with the key in locked position.

The illustrative form comprises a spring wire ring member designated 10 which is adapted to hang loosely about the handle 11 of the door knob 12, in order that the same may be removed when it is desired.

The escutcheon plate 13 is provided with a key hole 14: in which a key 15 is inserti'ble and as shown in the drawings, is arranged in a locked position. A. key engaging member designated generally by the numeral 16 has the upper part of its barrel-like body portion formed with an opening 17 for loosely accommodating the ring member 10 so that the member 16 will be suspended from the ring memben A spring'pressed pair! 1% is slidably mounted in the opposite end of the body portion ofthe member 16 and is designed to removably close the hook-like engaging end 18 of the body portion, being operable by means of the knob 19.

The operation of my invention is as follows: After the key member has been inserted in the lock member, and locked the fastener is secured thereto which will retain the same in rigid position and prevent any one on the outside from removing the key. Furthermore my invention is adapted to retain the key when not in locked position thus preventing the same from being misplaced.

It will be observed upon reference to the accompanying drawings that the key engaging member 16 is desirably constructed in the form of a snap hook, the advantage being that the same can be manufactured separately and provided with the openings for accommodating the ring member 10 to provide the improved key fastener, the primary advantage of the device being the peculiar arrangement of these two parts namely, the members 10 and 16 for detachable engagement respectively with the door knob and a key when in a locked position, for preventing the surreptitious movement of the key to an open position.

It will now be apparent that I have devised anovel and useful construction as a key fastener, which embodies the features of advantage enumerated as desirable in the state ment of the invention and the above description, and while I have, in the present instance, shown and described the preferred embodiment thereof which was found in practice to give satisfactory and reliable result, it is to be understood that the same is susceptible of modification in various parupper Pfdlt of which is formed With an openpawl slidably mounted in the body portion ing for accommodating the ring to consefor removably closing the hook.

quently suspend the engaging member from In testimony whereof, I affix my signature the ring, a hook formed on the opposite hereto.

terminal of the body portion and adapted to engage the eye of a key, and a spring pressed V I PAUL T. ULRICH.
